    Can a Signal Event Have Incoming Arrow?

    Bruce Cui Newbie

      Hi,

       

      Actually I can have an incoming in my editor. But I see in the user guide where it says that "

      A Signal Event should have no incoming connections and one outgoing connection. "

       

      I tried to test the one with incoming arrow, and it appears to function like the previous process will step in a waiting status for defined signal, and this event will only react to the signal sent by the previous step.

       

      Plz let me know if my understanding is correct on this.

          Yes, it is a recent extension that a signal event can also have an incoming connection.  After it has been triggered, the event node will wait until the signal is received before continuing.

           

          Not sure though what you mean with "will only react to the signal sent by the previous step"?

            Thanks Kris. The one you mentioned was something I found in the testing, but was later proved a misunderstanding. But in the other hand, I noticed those Signal Events which were also defined to catch this signal, but did't have incoming arrows, did't respond to the signal raised in the main process, which the one with incoming arrow did respond to it.

             

            Not sure if you got what I mean. This might be another misunderstanding. But for now it's the smallest thing that is bothering me. If you check my other posts, for now I really need to know how to send a signal out from a WorkItemHandler, and any threads it started.

             

             

            Thanks,
